BACKGROUND OF THE INVENTION

Hand-held electronic scales for weighing objects, such as fish, areknown in the art. These prior art electronic scales include a displayassembly, which is non-pivotally connected to a handle assembly. A hookextends below the handle assembly for supporting an object, such as afish, to be weighed. The weight of the object is displayed on thedisplay assembly. Because of the limited viewing angle of the prior artdisplay assembly, the scale must be maintained at a predeterminedheight, relative to the individual's eye-level when the individual isviewing the display assembly. This limited viewing angle can makeweighing large objects difficult because it requires the individual toraise the scale and the attached large object to a predetermined heightfor viewing the display.

For this and other reasons, a need exists for an electronic scale forweighing objects, such as fish, which does not have to be maintained ata certain predetermined position relative to the individual's eye-levelfor viewing by the individual. It is to such an improved scale which thepresent invention is directed.

SUMMARY OF THE INVENTION

In one aspect, the present invention is directed to a hand-held fishscale having a pivotal display assembly for weighing objects such asfish. The scale includes a handle assembly which is dimensioned to begripped by the hand of an individual. The scale has an upper end and alower end. A force sensor is housed within the handle assembly. Asupport assembly having a support member connected to one end of aflexible linkage is provided for supporting the object. The flexiblelinkage is connected to the force sensor such that the flexible linkagetransfers the weight of the object supported on the support member tothe force sensor. In one aspect of the present invention, the flexiblelinkage extends from the lower end of the handle assembly such that thesupport member is supported below the handle assembly.

The handle assembly is pivotally connected to a display assembly suchthat the display assembly may be positioned at an optimum viewing anglerelative to the eyes of the individual supporting the handle assembly.An electronic display is disposed within the display assembly such thatthe electronic display can be perceived by the individual. Theelectronic display is electrically connected to a micro-controller,which may be disposed within the display assembly if desired. Themicro-controller is electrically connected to the force sensor forreceiving signals from the force sensor, which are indicative of theweight of the object. In response thereto, the micro-controllergenerates a value representing the weight of the object. The display isadapted to exhibit a readout of the value received from themicro-controller, which may be an alphanumeric representation of theweight of the object.

In another aspect, the present invention is directed toward a method ofusing an electronic scale. The method includes the step of attaching afish to be weighed on a support member suspended from a handle assemblyof the electronic scale. The handle assembly of the scale is thengripped by the hand of an individual and lifted so as to support orsuspend the fish, which is attached to the support member, to transferthe weight of the fish to a force sensor communicating with the supportmember. A display assembly, which is attached to the handle assembly, isthen moved relative to the handle assembly to bring the display of analphanumeric readout representing the weight of the fish within view ofthe individual.

Other features, and advantages of the present invention will be apparentto those skilled in the art from the following detailed description whenread in conjunction with the accompanying drawings and appended claims.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings, and more particularly to FIGS. 1 and 2,shown therein is a scale 10 constructed in accordance with the presentinvention for weighing at least one object 11, such as a fish (as shownin FIGS. 4 and 5). The scale 10 includes a display assembly 12, a handleassembly 14, and a hinge assembly 16. The hinge assembly 16 movablyconnects the display assembly 12 to the handle assembly 14 such that thedisplay assembly 12 can be moved relative to the handle assembly 14, toprovide an angled focus for viewing by an individual 18 (as shown inFIGS. 4 and 5) to be described hereinafter. In one embodiment, the scale10 can be a hand-held electronic fish scale.

The handle assembly 14 includes a housing 19 having an upper end 20 anda lower end 22. The housing 19 can be formed from a front piece 24 and arear piece 25. The housing 19 of the handle assembly 14 is contoured tobe gripped by the individual 18 so that the individual 18 cansubsequently lift the scale 10 and the object 11 supported thereby. Thehousing 19 can be constructed of a sturdy yet lightweight material, suchas a polymeric material. The rear piece 25 and front piece 24 areattached to form the grippable exterior portion of the housing 19 of thehandle assembly 14 using known methods, such as a bonding material orscrews.

The housing 19 encloses an interior space 26. The interior space 26defines a first pocket which is sized and dimensioned to matinglyreceive a power supply housing 27 therein. The power supply housing 27is adapted to retain a power supply (not shown) to provide electricalpower for the scale 10. The interior space 26 defines a second pocketwhich is sized and dimensioned to matingly receive a force sensor 28therein so that the force sensor 28 is supported by the housing 19 ofthe handle assembly 14. An opening 30 is provided through the lower end22 of the housing 19 such that the opening 30 communicates with thesecond pocket defined by the interior space 26.

A support assembly 31 is provided for permitting the object 11 to besupported thereby during weighing of the object 11. The support assembly31 includes a support member 32 connected to a flexible linkage 34. Theflexible linkage 34 has a first end 36 and a second end 38. The flexiblelinkage 34 can be constructed of a rigid, yet flexible, material such asmetal chain. The first end 36 of the flexible linkage 34 is disposedthrough the opening 30 formed through the lower end 22 of the handleassembly 14, and is connected to the force sensor 28. The second end 38of the flexible linkage 34 is connected to the support member 32. Thesupport member 32 can be provided with a hook shape, and can also beconstructed from a rigid material, such as metal. Thus, it can be seenthat the force sensor 28 supports the support assembly 31 such that theweight of the object which is being supported by the support member 32is translated into a force applied to the force sensor 28.

The force sensor 28 outputs electronic signals indicative of the weightbeing supported by the support assembly 31 over a first signal path 40extending between the force sensor 28 and a micro-controller 50, whichcan be located in the display assembly 12, as shown in FIG. 1. Themicro-controller 50 is capable of receiving signals representing theweight of the object from the force sensor 28 and generating valuesindicative of the weight of the object 11 for communication to anelectronic display 52. The micro-controller 50 and the electronicdisplay 52 can be a conventional electronic display andmicro-controller.

The electronic display 52 is at least partially contained within a firstopening 54 formed in a front facing 56 of the display assembly 12 suchthat the electronic display 52 is perceivable by the individual 18. Theelectronic display 52 is electrically connected to the micro-controller50 such that the electronic display 52 is capable of receiving signalsfrom the micro-controller 50 and displaying an alphanumeric readoutrepresenting the weight of the object 11.

To selectively actuate and deactuate the scale 10, the display assembly12 includes a power switch 58 which initiates and terminates power fromthe power supply retained within the power supply housing 27 through asecond signal path 60. The second signal path 60 extends from theinterior space 26 of the handle assembly 14 through the hinge assembly16 into the display assembly 12. The power switch 58 is disposed througha second opening 62 in the front facing 56 of the display assembly 12 tobe accessible to the individual 18.

Referring now to FIG. 3, the hinge assembly 16 will be describedhereinafter. The hinge assembly 16 includes a first flange 66 and asecond flange 68 extending upwardly in close proximity to the upper end20 of the handle assembly 14. The first and second flanges 66 and 68 arespatially disposed to form a void 70 therebetween. A first flangeopening 72 and a second flange opening 74 are formed in respective firstand second flanges 66 and 68 such that the first and second flangeopenings 72 and 74 communicate with the void 70.

A hinge member 76 having a first side 78 and a second side 80 projectsfrom the lower end of the display assembly 12 and is disposed in thevoid 70. A first pin member 82 projects from the first side 78 of thehinge member 76 so as to pass through the first flange opening 72. Asecond pin member 84 projects from the second side 80 of the hingemember 76 so as to pass through the second flange opening 74.

Thus, the first pin member 82 disposed through the first flange opening72 and the second pin member 84 disposed through the second flangeopening 74 are constructed to maintain the display assembly 12 movablyconnected to the handle assembly 14. The hinge assembly 16 allows forlimited movability along an axis of rotation 85 of the display assembly12 relative to the handle assembly 14 so as to provide an angled focusfor the individual 18 to overcome the limited viewing angle of the priorart electronic display.

A stop pin 86 (not shown in detail) projects from the first pin member82. The stop pin 86 is positioned to contact the interior of the housing19 when the display assembly 12 is movably rotated to a forward-mostupright position relative to the handle assembly 14. The stop pin 86contacts the interior of the housing 19 to limit the rotation of thedisplay assembly 12 beyond a forward-most upright position relative tothe handle assembly 14.

The housing 19 of the handle assembly 14 defines an angled uppershoulder portion 90 such that a front shoulder portion 92 is raisedabove a rear shoulder portion 94. An angled lower shoulder portion 96 isdefined by the display assembly 12 such that a front shoulder portion 98is disposed lower than a rear shoulder portion 100. Thus, it can be seenthat the inverse angled relationship of the angled upper shoulderportion 90 of the handle assembly 14 and the angled lower shoulderportion 96 of the display assembly 12 matingly come into contact whenthe display assembly 12 is tilted relative to the handle assembly 14. Inother words, the angled upper shoulder portion 90 of the handle assembly14 becomes a support platform upon which the angled lower shoulderportion 96 of the display assembly 12 is supported when the displayassembly 12 is disposed in its most acutely pivoted position relative tothe handle assembly.

Referring now to FIGS. 4 and 5, the movement of the display assembly 12relative to the handle assembly 14 is described. The display assembly 12is pivotally connected to the handle assembly 14 so as to permitmovement of the display assembly 12 relative to the handle assembly 14between a first position and a second position. In the first position,as shown in FIG. 4, the display assembly 12 is disposed in an uprightposition such that the front facing 56 of the display assembly 12 isaligned with the front piece 24 of the handle assembly 14. In the firstposition, the electronic display 52 can be read when the electronicdisplay 52 is generally disposed at a same height as the individual'seyes.

In the second position, as shown in FIG. 5, the display assembly 12 isdisposed such that the front facing 56 of the display assembly 12 is atan obtuse angle relative to the front piece 24 of the handle assembly14. The positioning of the display assembly 12 relative to the handleassembly 14 allows the electronic display 52 to be read from an optimumlocation generally below the eyes of the individual 18. Thus, theshortcomings of the limited viewing angle of the prior art scales isovercome with the pivotability of the display assembly 12 relative tothe handle assembly 14 of the present invention.

In use, the individual 18 attaches the object 11 to the support member32. The individual 18 lifts the scale 10 and the object 11 attachedthereto to support the fish whereby force is applied to the force sensor28 and the electronic display 52 is disposed at an angle relative to theheight of the individual's eyes. The micro-controller 50 receives thesignals output by the force sensor 28 and translates these force signalsinto a signal indicative of the weight of the object 11. The signalindicative of the weight of the object 11 is generated by themicro-controller 50 and output to the electronic display 52 connectedthereto, so that such signal is displayed as an alphanumeric readoutwhich is visually perceivable by the individual 18. The display assembly12 can then be pivoted relative to the handle assembly 14 to an optimumviewing angle such that the electronic display 52 is in view of theindividual's eyes.
